WebJan 10, 2024 · You can use the z-score tables to find the z-score that corresponds to 0.025 p-value. In this case, it is 1.959. Once you have calculated the Z (0.95) value, you can simply input this value into the equation above to get the margin of error. Now, the only thing left to do is to find the lower and upper bound of the confidence interval: WebJan 20, 2024 · Z Scores! The z score is used when we standardize a bell curve.

WebSo we're starting at 50% here. We definitely want to get to the 67%, 68, 69, we're getting close and on our table this is the lowest z-score that gets us across that 70% threshold. It's at 0.7019. So it definitely crosses the threshold. And so that is a z-score of 0.53. 0.52 is too little. So we need a z-score of 0.53. is the grateful dead still touringThe first column of a z table contains the z score up to the first decimal place.
